Door stopper

Counterweight

Installation

The length of the counterweight box is designed to suit the max. door weight (10, 15 and 20 kg). A space is left in the upper area of the box when it is filled to the max. capacity. This space allows fine adjustments to be made when installed. i.e. weights can be removed or added.

If the max. door weight is less than the selected maximum weight, the box can also be shortened. A space of at least 70 mm is needed to make fine adjustments.

The boxes must be filled with the same amount of weight.

Note

The height of the counterweight box must be calculated. If necessary, order 2 boxes and mount one on the left hand side and the other one on the right hand side.
